HALF-PRODUCT BASED ON PREIMPREGNATED FIBRES WITH POLYMERISABLE RESIN |
摘要 |
The invention relates to a semi-finished product based on fibers preimpregnated with polymerizable resin, which is intended for the manufacture of components made of composite materials and having a variety of shapes, in particular long and/or thick components. This semi-finished product comprises at least one layer formed of a plane web of preimpregnated fabric and of a web of strips of preimpregnated rovings arranged in rows juxtaposed on the fabric in one and the same longitudinal direction. Another web of preimpregnated fabric is preferably provided. It passes alternately above and below the rows of strips. The fibers of the rovings and of the fabrics can be glass fibers, carbon fibers, boron fibers or Kevlar fibers. |
